The recording is ok for a few seconds

Moto G5s plus, android 7.1
Unfortunately there is a bug with Android 7.1.1 that prevents call recording working reliably.
Setting recording delay to 3 or more seconds seems to help but not always.
This is same on all call recording apps and we hope will be fixed on Android 8
